In Su's mind she should probably be using more of her skills to ensure the safety of those around her. She had been wondering what else she could do in situations like this to help others.
The natural idea was that she would be able to learn more from the cathedral. Or she would have to speak to the dragons about how they strengthen the dragonkin who work with them. Whether they are leading them to a task, the dragonkin naturally seem more energized.
Whether that is the mana that they radiate or the fact that they are using some sort of buffing skill didn't matter. If Su could take on some of those skills or similar she could be making all the guards and soldiers here with her stronger and in turn, making herself more useful.
As she watched, this thought began to run through her mind and even more so when she looked at the focused faces of all those who stood with her. The shields prepared could be made stronger.
